Just by the name, you can probably tell they're great for maintaining frequency stability in applications. But what specific applications require very high stability to perform optimally?  In this blog, we'll discuss the top four applications for ultra-stable oven controlled crystal oscillators (OCXOs).

Should you use a standard oscillator (OCXO), a GPS disciplined oscillator (GPSDO), or an atomic clock in your satellite? The short answer is, "it depends." You'll need to choose your timing device based on on your specific needs, limitations, and operational orbit. Let's take a look at each operational orbit (LEO, MEO, and GEO) and which types of timing devices their satellites require.

Yes, simple oscillators like those made with resistor-capacitor (RC) or inductor-capacitor (IC) resonators are fine for some circuits. But if you're dealing with higher performance applications in the aerospace, military, and space industries, you're going to want a higher performance crystal oscillator that can maintain low phase noise and strong stability. Otherwise, you'll risk deviating from the very specific (and usually critical) center frequency selected for your design. In this blog, we'll discuss how to measure low phase noise and how to maintain it in your applications.

These powerful devices (sometimes called GPS clocks) consist of a [high-quality stable oscillator](https://www.bliley.com/high-performance-oscillators?on=us) and a GPS receiver. The GPSDO works by disciplining (or steering) the oscillator output to a GPS device or GNSS satellite signal via a tracking loop.
